Reading this it will get clear that a protecting grille for hopper windows is a must have for cat owners.
This is my first try to make this protections by myself. It is designed for standard windows with a gap of 16cm on the upper corner. Because I have plastic windows I can't use screws. But with thin transparent double sided adhesive tape by 3M the grilles stick strong enough on the window. The foot of the grille will be pressed to the windows frame by the seal of the closed window if it is mounted in the direction shown of the photo. So it is stable enough for curious cats. If the feet will not fit under the seals you can change the left with the right models and place the feet outside of the windows seal area.
Edit 2017/09/23: Added models with screw holes for those who want to fix the parts with screws on the windows frame
Edit 2017/09/24: Added models "Top" for the upper gap of the windows to prevent the escape of the fur noses if they are now using the grille as ladder
